If the damper lever is moved aw= ay from the spoon when the hammer is in check (whether by hand or with the l= ift rod) it has no effect on anything else in the action (unless it's hitting= a neighboring damper) and could never affect the whippen or anything connec= ted to the whippen unless it actually held the spoon in some manner like a bu= rr in the spoon catching (holding) the lever felt just enough to prevent the hammer to drop... but I think that the force holding the spoon to the lev= er has to be greater than the downward force of the hammer and whippen. The burr in the spoon has to be holding the felt pretty good to counter the hammer & whippen falling... maybe it's a VERY small nick in the spoon but enough to catch the felt 1 out of 50 times. I'd try polishing the spoon a= nd treating the lever felt and see what happens after 51 times. =0D =0D Larry Trischetta, Pocono NE Chapter=0D =0D -------Original Message-------=0D =0D From: Pianotech=0D Date: Thursday, May 15, 2003 00:59:32=0D To: Pianotech=0D Subject: A New Trouble=0D =0D I ran into a new one today. A brand new Henry F. Miller grand that probab= ly was not prepped at the store. I did ease all the keys as many bushings we= re tight and quite a few balance hole tight as well. After all of that, I st= ill had a sticking key. It was C3, (3rd key from the top of the bass), that would stick but only on occasion. It might play 30 to 50 times normally, = and then stick down with the hammer in check on the backcheck. I then discove= red that by slowly pressing the damper pedal, the hammer would release from t= he backcheck and then with a little more movement of the damper pedal, everything would drop back to normal. The hammer and the backcheck look o= kay I believe that the key end and the damper underlever are somehow stickin= g but could find nothing out of the way like a burr or something. The key d= oes lift a spoon on the damper underlever and the felt on the key and the spo= on look very good. Looking for ideas.=0D =0D Norm Barrett=0D Memphis chapter=0D =0D _______________________________________________=0D pianotech list info: https://www.moypiano.com/resources/#archives=0D =2E=20 --------------Boundary-00=_MN40LVC0000000000000 An HTML attachment was scrubbed...
